Use the following commands to mount and install Matlab. Note that the path to the install script should contain no spaces, or the install will fail. For graphical install and interface {{Pkg|libxp}} is needed. You may need to [[Pacman|install]] {{Pkg|libxp}} from the [[official repositories]] first. Note also that Matlab is not compliant with Java 7, so you may need to install, for example, {{Pkg|openjdk6}}.

Install from iso file:

# modprobe loop

# mount -o loop matlab.iso /mnt/

# /mnt/install

−

pacman -S libxp

Additionally, install {{Pkg|xorg-fonts-100dpi}}, {{Pkg|xorg-fonts-75dpi}}, and {{Pkg|xorg-fonts-type1}} so fonts are displayed properly in figures.

These are instructions for the installation of 32-bit Matlab on a 64-bit system. Unfortunately, 32-bit is the only version available to students; 64-bit versions are available if you pay more money. These instructions have been updated for the student r2009A version - however the instructions should work with any current version of Matlab. To start off with we need to install a bunch of lib32 packages, not all found with pacman. Check the [[AUR]] for lib32-printproto, lib32-libxp and lib32-libxpm. Install lib32-printproto first, because it's required by lib32-libxp.

If you choose Custom in Installation Type, the symlink will be created automatically. Otherwise, you may need to manually create a symlink in {{ic|/usr/local/bin}} to make it easier to launch in terminal:

Then create a new .desktop file in {{ic|/usr/share/applications}} with following lines:

$ yaourt -S lib32-libxp

To identify this error, start MATLAB with

version `GLIBCXX_3.4.15' not found (required by /usr/lib/xorg/modules/dri/swrast_dri.so))

+

+

then the problem is that MATLAB uses its own GNU C++ library, which is an older version than the up-to-date version on your Archlinux system. Make MATLAB use the current C++ library for your system by

+

+

cd /usr/local/MATLAB/R(your release)/sys/os/glnxa64

+

sudo unlink libstdc++.so.6

Once Matlab is installed type the following in the interpreter:

The output should be similar to the following:

This will vary with card you are using, but the important part is "Software = false". If it's not "false" for you, then there is a problem with your hardware acceleration.

With the NVIDIA card all it required to start working was to copy the {{ic|libGLU.so}} from the Matlab installed library {{ic|${MATLAB}/sys/opengl/lib/glnx86/libGLU.so}} to {{ic|/usr/lib directory}}. Note that in x86_64 this might be a different directory.

That is what it should look like. If you have a graphics card but it is using Software = true then you have a problem. With the nvidia card all I needed to do to get it working was copy the libGLU.so from the matlab installed library /usr/local/matlab/sys/opengl/lib/glnx86/libGLU.so to /usr/lib directory. NOTE in x86_64 this might be a different directory.

Notes:please use the first argument of the template to provide more detailed indications. (Discuss in Talk:Matlab#)

General installation

Use the following commands to mount and install Matlab. Note that the path to the install script should contain no spaces, or the install will fail. For graphical install and interface libxp is needed. You may need to installlibxp from the official repositories first. Note also that Matlab is not compliant with Java 7, so you may need to install, for example, openjdk6.
Install from iso file:

After fixing any library dependency problems, you will be able to guide the installer through the install process. If activation doesn't work in the installer you'll need to login to Wolfram's site and download a license file which you'll put in ${MATLAB}/licenses. After the install process, you'll need to create a symbolic link because the installer oddly thinks it's installing the 64-bit version of Matlab:

$ cd ${MATLAB}/sys/java/jre
$ ln -s glnx86 glnxa64

In the above, ${MATLAB} should be replaced by the root directory you chose for your installation.

You'll also need to put another link in Matlab's bin folder because despite asking Matlab to install the 32bit version, it still thinks you want to use the 64bit one:

$ cd ${MATLAB}/bin
$ ln -s glnx86 glnxa64

After that you'll need to edit the ${MATLAB}/bin/matlab script to get the java settings correct. After the comments at the top of the file, you'll need the line:

export MATLAB_JAVA=/path/to/jre

Where /path/to/jre will be /opt/java/jre if you're using Sun's JRE. The path is one level up from where rt.jar is located. That is, rt.jar should be in /opt/java/jre/libs if you used /opt/java/jre for MATLAB_JAVA. In Matlab R2010a it works pretty well, if you use the internal JRE with:

At this point you may have to resolve more library dependencies or troubleshoot Java. Your version of Matlab may need a specific version of Sun's JRE installed.

Install supported compiler

In order for Matlab to work with C code it is necessarry to install a supported Compiler. Install gcc44AUR from the AUR.

Then edit ${MATLAB}/bin/mexopts.sh and replace all occurances of CC='gcc' with CC='gcc-4.4' and CXX='g++' with CXX='g++-4.4'. Afterwards run

mex -setup

in Matlab and select the mexopts.sh file.

Troubleshooting

As one installs Matlab, it might complain that it can't find a package, for the most part just look at the package name and then install it with Pacman, or in the case of x86_64 there are some libraries only in AUR.

Resolving start warnings/errors

Even if all needed libraries are installed, Matlab when starting can still report some missing libraries. This is resolved by symbolic linking of needed libraries to directories that Matlab checks at start-up. For example, if Matlab triggers error/warning about missing /lib64/libc.so.6 library, this can be resolved by:
